3 Claims. (Cl. 240-73 The ipresent invention has for its primary object to produce a simple, attractive and inexpensive electric lamp which may -'-be hung on a wallor be set on=a tableor the like near a wall, and which may easily be altered by the user to harmonize with any color scheme in its surroundings.

In carrying out my invention I employ a shade behind which is concealed a light bulb in a socket mounted on a light frame structure attached to the shade.

A subsidiary object of the invention is to produce a novel shade that determines the color of the light emitted by the lamp and facilitates changes to vary such color.

In carrying out this latter object, I form the shade in two parts one of which is a thin rigid panel, while the other is a liner or backing comprising a fairly stiff sheet of flexible, elastic material. The panel is opaque but is perforated according to any desired design and to the extent that illumination is desired. The liner is translucent and is detachable so that, by providing liners of different colors, a change in the color of the light may be effected quickly and easily.

The various features of novelty whereby the present invention is characterized will hereinafter be pointed out with particularity in the claims; but for a full understanding of the invention and its various objects and advantages, reference may be had to the following detailed description taken in connection with the accompanying drawing, wherein:

Fig. 1 is a front view of a lamp embodying the present invention;

Fig. 2 is a rear view of said lamp;

Fig. 3 is a top plan view of the lamp, looking down with the lamp in the position shown in Fig. 1;

Fig. 4 is a section on line 44 of Fig. 3, showing only the frame and the cross pieces;

Fig. 5 is a bottom plan view, on a larger scale, of a fragment of the shade at one of its vertical edges; and

Fig. 6 is a face view on a large scale, of a corner of a fiat, perforated plate which may be used for making the rigid panel member of the shade.

Referring to the drawing, 1 is a stiff rectangular panel, preferably of thin metal plate material, perforated across the length and width thereof. Only a few of the perforations 2 are shown in Fig. 1, but the whole preferred design is shown in Fig. 6. Member 1 is curved in the form of a segment of a cylinder. The marginal portions 3, along the vertical edges, are folded rearwardly and inwardly as shown in Fig. 5, to provide at each such edge a channel or groove 4.

Fitting against the concave surface of panel 1, and extending at its vertical margins into channels 4, is a rectangular, translucent liner 5, the vertical dimension of which is preferably somewhat less than the height of panel 1, as shown in Fig. 2. The transverse dimension of the liner is such that it is compelled to lie against and closely follow the contour of the panel. This liner may be a translucent sheet of any suitable material that is 2,824,216 Talented Feb. 18, 1958 the-liner to beflexed'and sprung into and out. of the channels without being stressed beyond its elastic limit. The

liners are made in various colors.

.The shade is provided with means to support a light bulb gpositioned behind the same. In the arrangement shown, such means consists of two little rectangular frames composed of strip material, 6, 6, and a pair of crosspieces, 7 and 8, of somewhat wider material. The long dimension' of the openings in the frames is equal to the height of the shade, so that the latter may extend through both-frames and-fit against the inner side of one of the long members of each. The cross pieces 7-and 8 are welded or otherwise fixed to the other long members of the :frames in such a manner that the planes of the frames converge from fronttorear and are radial to the shade. IThepanel element -of the shade is welded or otherwise fixed to the long frame members with which they engage so that the whole forms a rigid unit. The framework preferably extends rearward somewhat beyond a vertical plane containing the vertical edges of the shade, so that these edges are clear of any wall against which the lamp is placed.

In the space between the cross pieces. 7 and 8 and the shade is a socket 9 for a light bulb 10, the socket being attached to the lower cross piece 8. The parts are preferably proportioned to bring the light bulb sufliciently close to the shade to prevent the liner from being removed without damaging the sarne, while the bulb remains in the socket; whereas, with the bulb removed, the liner may be flexed, in a manner to avert damage, sufiiciently to allow an end of the liner to be drawn out of the channel. So, also, one end of the liner may be inserted in one of the channels and the liner be then flexed to enable the other end thereof to spring into the other channel; thereby causing the liner to be self retained, namely, to be securely held in place in intimate contact with the concave face of the rigid panel.

The lamp may stand upright on a horizontal surface or be hung on a wall. To permit the latter form of support the upper cross piece 7 has at its middle a hole 11 to receive a nail, hook or other projection from a wall or other vertical member.

The combined heights of the socket and bulb, assembled, is less than that of the shade, so that the top of the bulb may be well below the upper edge of the shade and the socket may be a substantial distance above the bottom edge of the latter.

The esthetic value of the lamp is readily perceived. Liners of any desired color may be used with the same or a different coloring on the front face of the shade; or the rigid panel may be painted a different color Whenever necessary to create harmony with an altered. color scheme in the surroundings, or is desired to be of the same color as the liner.

I claim:

1. A lamp shade in the form of a rigid, vertical panel and a single detachable liner on the rear side of the panel, the vertical marginal portions of the panel being folded back to form two channels in which the ends of the liner are seated; the panel being a segment of a cylinder, being opaque and being perforated for the passage of light therethrough; and the liner being translucent and following the curvature of the panel when engaged in the channels and being suificiently elastic to permit flexing thereof, without stressing it beyond the elastic limit, in attaching it to and detaching it from the pane 2. A lamp comprising a shade in the form of a vertical perforated panel curved in horizontal cross section and folded back at the opposed vertical edges to form channels facing each other, a supporting structure behind the the front vertical leg of each frame, a stiiL'eIastic, translucent liner engaged at itsends in said chan'nels and fitting the curvature of the panel, the liner being approximately as high as the panel, the frames converging from front to rear, cross pieces rigidly connecting the rear Vertical legs of the frames, and a socket for a lightbulb connected to one of the cross pieces and standing in front of the same.

3. A lamp composed of a shade in the form of a rigid panel and a lining therefor; the panel being vertical,

curved in horizontal section, having the marginal portions folded inwardly on the concave side to form two vertical channels and being perforated to permit the passage of light therethrough; the liner being translucent, following the curvature of the concave side of the panel, fitting at its ends into said channels and being stiff while sufficiently elastic to permit it to be sprung into and out of said channels without being stressed beyond the elastic limit; an open frame structure fixed to the panel and forming a base and a frame structure which consists of two vertical, rectangular frames that embrace the shade, with the convex face of the panel contacting and fixed to one vertical leg of each frame, and cross pieces connecting the other vertical legs of the frames, whereby the two frames serve to prevent the liner from escaping upwardly or downwardly from the panel.
